Laboratory and semifield data indicate that vector Culicoides spp. in Florida are susceptible to permethrin.

ABSTRACT: The genus Culicoides includes numerous species that are biting nuisances and vectors of pathogens affecting humans, livestock, and wildlife. For instance, Culicoides paraensis is the primary vector of Oropouche virus to humans, while other species, such as Culicoides sonorensis, Culicoides insignis, and Culicoides venustus transmit viruses causing hemorrhagic disease in ruminants, particularly bovids and cervids. Current control practices for biting midges rely heavily on chemical insecticides, yet their efficacy and potential for insecticide resistance in biting midges remain poorly documented. We conducted laboratory and semifield experiments to evaluate permethrin susceptibility in wild biting midges collected on 5 Florida deer farms, including known and suspected hemorrhagic diseasevec
